Diesel Exhaust Fluid (DEF)

Makizh DEF is not a fuel additive. It is the essential fluid for every modern diesel engine with SCR technology – engineered to reduce harmful NOx emissions and keep your engine running at peak efficiency.

What is DEF?

Diesel Exhaust Fluid (DEF) is a non-toxic, colourless solution made of 32.5% high-purity automotive-grade urea and 67.5% de-ionized, de-mineralized water. It is a mandatory requirement for all BS6 diesel vehicles equipped with Selective Catalytic Reduction (SCR) technology – from trucks and buses to construction equipment and premium SUVs. Without high-purity DEF, your SCR system cannot function. The result is higher emissions, reduced power, and costly system failure. At Makizh Automotives, we manufacture DEF to the highest global standard of purity.


  1. Injection: A precise amount of Makizh DEF is injected into the exhaust stream.
  2. Reaction: Inside the SCR catalyst, the heat breaks DEF down into ammonia and CO2.
  3. Reduction: The ammonia converts harmful Nitrogen Oxides (NOx) into two harmless elements – pure Nitrogen and Water Vapour – which exit the tailpipe.

The Result?

Your vehicle meets emission norms without compromising on engine power.
